Description
The SKY85728-11 is a highly integrated, 5 GHz front-end module
(FEM) incorporating a 5 GHz single-pole, double-throw (SPDT)
transmit/receive (T/R) switch, a 5 GHz high-gain low-noise
amplifier (LNA) with bypass, and a 5 GHz power amplifier (PA)
intended for high-power 802.11ac applications and systems.
The LNA and PA disable functions ensure low leakage current in
the off mode. An integrated power detector is included to provide
closed-loop power control within the system.
The device is provided in a compact, 24-pin 3 x 5 mm Quad Flat
No-Lead (QFN) package, which may reduce the front-end board
space by more than 50 percent. A functional block diagram is
shown in Figure 1.
